5/8" Ball Transfers Units 5Pcs Screw Mounted Metal Roller Ball Transfers Bearing,for Table Conveyor Transmission System

Great product great price would definitely buy again

I recently bought this for a robot that I am on working as a hobby. The ball bearings are good quality and move well. This is easy to install and it is very sturdy to use. The value is great as well!

I really wish I could give these a great review, but even though they are a good idea in theory, they fail miserably in the real world. Yes, they look good. They are easily mountable. And the price is cheap enough. However,,,, they just can’t handle any type of real weight being put on them and still be able to roll. They just tend to skid across my smooth tile floors. Yes, they only just “skid” on the floor. Plus, they also tend to get debris caught up in the ball bearing making them even worse. Now they claim to have a weight limit of around thirty pounds, but I can tell you now that 30 pounds isn’t really very heavy and if something only weighs 30 pounds I would highly doubt it would need these screw mounted to the bottom of it to move around easily. Plus, if they are only going to skid and not roll, then you might as well just skid the item itself without these bearing rollers. I just figured that if they have a weight limit of 30 pounds, and I use 5 of them, then the weight limit should be 150 pounds. No! I didn’t even put 50 pounds on all 5 and they were worthless. And don’t even think about using these on any type of carpet. That would be nonsensical at best. I wouldn’t suggest buying these at all for anything. I would just buy some mini swivel caster wheels and call it a day. To be honest, I don’t even really think they are worth the two stars I’m giving them. As a matter of fact, I’m changing it to 1 Star right now.

They work well enough but I attached them under my dogs crate to make it movable to vacuum around. Unfortunately, when sliding it out, it sounds like nails on a chalkboard against my concrete floor.

Mounted these on coffee table legs and it works great without raising table too much. Sturdy

Used on old table saw. Used to easily roll after folded up under bench.

They are easy to install but they aren't functional. The balls don't move smoothly so as rollers, they don't roll. I didn't bother using them because I can clearly see that the balls in the casters do not move freely.

These must be meant for a really light table. My living room coffee table is simply an average-sized wooden table and the stealing these things is already bent so bad it rubs against the wheel on every motion. These could be perfect for lighter duty stuff. I just can't think of anything that light

Need to change my previous review they arrived on time

I bought these casters to install on my Quickjacks. They made it easier to move around on the floor.They struggled a bit on a fairly smooth surface but in their defence the frames weigh 103 pounds.I think it was a goood buy.

It may not be recommended by safety professionals, but I glued these under my coffee maker with double faced tape so I can easily slide it on the counter to access the water well. Works awesome after months of using!

The ball don’t roll I damaged my wood floor with an item that wasn’t even a weight of 10 lbs even though those casters are rated for a lot heavier items .i would not recomand this item

I have a good condition concrete floor. These wheels did not work on that surface. Perhaps on smooth services they would perform well
